SBC (Sharding Byte Chain) is a new super public chain by using new generation of sharding storage technology. Its token symbol is SBC. It supports QEX pre-mining and uses POW+POS consensus mechanism to issue phase 1 main network. SBC features higher performance, node cluster, and provides an innovative sharding solution for nodes. Effective storage and data traceability can be achieved through on-chain index to support the release of commercial applications. The main network includes node inspection, lightning network, sharding storage, smart contract, wormhole encryption, payment gateway settlement, edge computing, Internet communication and base station deployment. SBC is expected to be a new product representing blockchain 4.0. The SBC super public chain will take the lead in a new consensus revolution, creating more efficient consensus algorithms. Working with developers around the world, we strive to achieve the development of modules in various fields of public chain application, the breakthrough of performance limit and the presentation of ecosystem through the huge community groups.
